Bug #2548: Validate deletion of host if that is used as a parent somewhere

Date: 2016-12-14State: openClass: nastinessComponent: wato

If you delete a host that is a parent of some other host thenyou should not be able to delete that host.The question is, if deleting of hole folders or even folder treesshould also be validated (complicated). Same holds for bulk delets.Here we would need to validate the situation after *all*deletes have been done.Suggestion: we validate just when deleting one single host.
